amazon web services - Extract date time from Apache Combined log format using AWS Logs and Cloudwatch -


we're using awslogs collect apache combined formatted logs cloudwatch. it's capturing fine, we're getting timestamp not parsed message error.

an example log entry:

::ffff:10.0.0.1 - blahblah [17/aug/2017:20:31:07 +0000] "get /favicon-16x16.png http/1.1" 304 - "http://blahblah:3000/" "mozilla/5.0 (macintosh; intel mac os x 10_12_6) applewebkit/537.36 (khtml, gecko) chrome/60.0.3112.90 safari/537.36"

our config set of log files looks this, including our datetime_format entry:

[access_logs] log_group_name = cromwell log_stream_name = react-172.31.43.245-access file = /home/admin/aperian-react/log/*access.log datetime_format = "%d/%b/%y:%h%m:%s %z" multi_line_start_pattern = ::ffff: time_zone = utc encoding = ascii

as can see, datetime mid-line. different examples syslogs, etc. change our log format, we'd prefer not since flow other systems well.

our dateformat_string missing colon.😒 😢

datetime_format = "%d/%b/%y:%h%m:%s %z"  # wrong datetime_format = "%d/%b/%y:%h:%m:%s %z" # correct

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
